Recently, in order to meet the stricter emission regulations, the proportion of after-treatments is increasing gradually. The aim of present study is to analyze the physico-chemical mechanism according to hydrothermal aging of 3Pt-2MgO-3ZrO₂-2CeO₂/Al₂O₃ DOC. After H₂PtCl?·6H₂O precusor was impregnated with γ-Al₂O₃, Pt particles were dispersed into 2~3nm small size, because γ-Al₂O₃ have a outstanding the dispersion force as well as the thermal durability. In the case of hydrothermally aged catalyst at 850℃ for 9h(10% H₂O), CeO₂ represented remarkably cohensive trend, the specific surface area of 114m²/g was reduced by 14% compared to Fresh catalyst. In the future, additive catalyst to avoid the agglomeration of CeO₂ will be investigated.
